One of the commonly used LED Tube driver chip is 74HC595, by using the Chip, you can save GPIO ports. I bought an LED Tube with 595 chip, it only needs 3 GPIO ports to display 4 digits. However, there is no existing posts about how to drive the 74HC595 LED Tube from Windows 10. So, I can only try for myself. …
If you need to precisely control the rotation angle of the equipment, ordinary motors can't do it, usually we use stepper motors. For example, the 28BYJ-48 model is easy to buy. The stepper motor has to be used with the driver board, and the most commonly used is the driver board ULN2003 the chip, as shown in the figure below. However, note that the driver board you buy may not look the same, but it doesn't matter, as long as the chip is written on the ULN2003, you can use it, and their interfaces are the same.
In many buildings, there are sound controlled light in use. When you clap your hands, the light turns on. Now, with Raspberry Pi 3 and Windows 10 IoT, we can make a sound controlled light ourselves.
The sound sensor I use is FC-04. As other sensors, the first step is calibration.
1. Calibration for FC-04 Sound Sensor
In quiet environment. Connect VCC to DC 3.3V,GND to Ground. At that time, the …
I bought a moisture sensor like this recently.
After some research, there seem no articles to indicate how to use it in Windows 10. So I figured out myself.
This sensor has 4 Pins, which are:
PIN
Usage
AO
Analog Out
DO
Digital Out
GND
Ground
VCC
Power
So, let's connect VCC to DC3.3v on RPi, I use PIN 01. Connect GND to any ground header, which I use …
I purchased a GY-30 light sensor recently, this model is also known as "BH1550FVI". There seems no sample for this sensor on Windows 10 yet, so I tried to make one.
The light sensor looks like this:
My board is a Raspberry Pi 3, the GPIO layout is shown in this table:
Because GY-30 is an I2C device, so we can not use GPIO to drive it directly, we must use the I2C ports. In addition, …
For those who have watched the "Big Bang Theory", you would probably remember that those physicists build an Internet controlled lamp. The signal send from their laptop traveled around the world and come back to their house to light up the lamp. Now, with Windows 10 IoT Core and Microsoft Azure, we could also achieve the same thing on a Raspberry Pi 3. First, I strongly recommend you to read …
